Ariflo  development of peripheral edema”limit the tolerability of endo thelin A receptor blockers and probably contributed to the decision to put development of darusentan on hold. Neverthele these findings raise the question of whether dual specificity AT R and endothelin A recep tor antagonists could be more effective and better tolerated than specific endothelin A receptor blockers. In a phase I randomiz double bli placebo controll and www.nature/nrcardio Macmillan Publishers Limited. All rights reserved REVIEWS active treatment controlled trial in patients with stage hypertensi PS reduced systolic and diastolic blood pres sures more effectively than place with the highest dose achieving a greater reduction than the AT R blocker irbe sartan.

In additi pared with irbesart all doses of PS were associated with improved rates of blood Phloridzin 60-81-1 pressure control at weeks. Although these results were encouragi they have not been published in a peer reviewed journ and clinical development of this agent has been suspended until amercial partner is found. Vasopeptidase and ECE inhibition Endothelin is produced by another metallopeptida ECE. The dual ECE and neutral endopeptidase inhibitor daglutril reduced both proteinuria and glomerulo sclerosis in rats with streptozotocin induced diabetes to an extentparable to the ACE inhibitor captopr an effect previously not observed with sole ECE inhibition. Although daglutril reduced pulmonary and right atrial pressure in patients with congestive heart failu this study was published in and more recent data on this substance are not available. Howev some other buy Formononetin dual ECE and neutral endopeptidase inhibito such as SLV , are in preclinical pipelines.

In stroke pro spontaneously hypertensive ra SLV treatment was well tolerated and associated with improved survival as well as a significantly lowered incidence of stroke. Howev the treatment did not have a significant effect on blood pressure. ination therapies Seliciclib CDK inhibitor Currently a single pharmacologic agent is sufficient to achieve adequate blood pressure control in only approxi mately one third of patients with hypertension; another one third will need two dru and the rest require at least three agents. These requirements are reflected in the current European guidelin which rmend the use of abination of at least two antihypertensive drugs in patients with mild to severe hyper tension. Trials of antihypertensive therapy in patients with heart failure have demonstrated that mortality can be reduced progressively by the inclusion of additional antihypertensive agents in the treatment regimen; mor tality was progressively reduced in the following trials: SOLV CIBIS II and RALE and CHARM . ination therapy provides superior blood pressure reduction because each agent typically blocks the counter regulatory system activity triggered by the other and might also attenuate its adverse effects.
